[vsnet-outburst 31671] TCP J07151825+4753167 and TCP J15030519+2202041: new hydrogen-rich and helium-rich WZ Sge-type dwarf novae
by Hiromasa Hoke 11 May '26

11 May '26

Dear all, We posted the photometric follow-up results by Itoh-san and Moriyama-san for TCP J15030519+2202041 and our spectroscopic follow-up results for TCP J15030519+2202041 and TCP J07151825+4753167 to ATel. https://www.astronomerstelegram.org/?read=17791 We concluded that J0715+4753 is a new WZ Sge-type dwarf nova because Hα has a narrow emission core and its spectrum shows a blue continuum with the Balmer and HeI absorption lines. J1503+2202 is a new AM CVn-type dwarf nova because this object has HeI absorption lines, a temperature of ~25,000K and possible early superhump period of 0.0303(1) d. Follow-up observations are important. Especially, TCPJ1503+2202 is a long-period AM CVn star, and the opportunity to observe such an event is rare. Continuous time-series observations are strongly encouraged. best regard, Hiromasa Hoke
